Nursing care for hospitalized older adults - fall accidents versus safe mobility: a scoping review

ABSTRACT Objectives: to map the constituent elements of the safe mobility concept present in hospital care for older adults. Methods: a scoping review of 35 articles searched in databases and gray literature - BDENF/VHL, Scopus, CINAHL/EBSCO, Embase, Web of Science, PEDro, MEDLINE/PubMed and CAPES Theses and Dissertations Catalog. No time or language cut-off was established. Results: none of the studies presented a clear safe mobility concept, however its constituent elements involve factors related to patient (behavioral factors, conditions, diseases, signs and symptoms, nutritional status, age, balance, strength, gait quality, sleep), the institution (environment, treatment devices, guidelines, medications and polypharmacy, material and human resources and clothing/shoes) and the nature of the interventions (related to the patient, institution and family). Final Considerations: the constituent elements of safe mobility express hospital units’ capacity to guarantee care and protection from fall accidents for hospitalized older adults.


INTRODUCTION
The occurrence of falls in older adults, despite continuous nursing efforts to reduce them, still represents one of the most important incidents in hospital environments, considering its frequency, economic impacts and consequences (1) .This situation arises from the fall prevention programs and protocols implemented, which tend to simplify the event and overvalue prevention itself, neglecting fall risk assessment in a care plan (2) .Consequently, there is a greater emphasis on summing up and recording the scores obtained through the application of fall predictive scales, while less time is dedicated to proposing interventions that address modifiable risk factors (2) .
During the last four decades, nursing practices related to fall prevention have not undergone significant changes (3) .Usually, the measures adopted focus on reducing patient mobility or improving environmental safety, without considering that intrinsic factors are, in fact, the main precursors to falls (2) .
However, interventions that limit mobility, such as signaling bracelets, recommendations for bed rest or reduced time spent using the toilet, despite offering some protection against falls, can lead to functional decline and the development of geriatric syndromes, such as instability postural, immobility and iatrogenesis (4) .Furthermore, such restrictive interventions increase the length of hospital stay, re-hospitalization risk and the likelihood of complications that, in turn, exacerbate future fall risk (4) .
During the hospitalization period, patients remain sitting or lying down on average 87% to 100% of the time (5) .Therefore, in older adults, even if healthy, ten days of bed rest are equivalent to a reduction of approximately 12% in aerobic capacity and 16% in the strength of the knee extensor muscles, which impacts a significant decline in functional capacity (2) .
In this context, the "safe mobility" concept expresses a transition in perspective, assessment and recognition of fall risk factors (2) .There is, therefore, an emphasis on intrinsic factors, without, in turn, disregarding protocols, predictive scales and extrinsic factors, which are also important, integrating evidence into care plan with an inter-and multi-professional approach (2) .
Safe mobility is centered on patients, valuing their individuality, preferences, needs and values (6) .Therefore, older adults are properly informed and consulted so that shared decisions can then be made that consider their wishes, technical issues and scientific evidence (6) .When older adults actively participate in planning their care, they can become aware of the risks and their own condition, which, in turn, motivates them to adopt safe mobility behaviors (6) .
This approach therefore implies greater critical thinking (2) .It is essential to carefully assess bed restriction guidelines, in addition to considering that preserving mobility may involve some risk of falling (2) .However, a realistic mobility plan may be more beneficial to older adults' well-being than the effort to avoid falls at any cost (2) .
Nurses, as care managers and influential agents in this context, play a fundamental role in preventing falls (7) .They are responsible for introducing and disseminating interventions that consider the individual needs of each older adult, aiming for their well-being, safety and autonomy (7) .From this view, clarifying the understanding of the constituent elements of the "safe mobility" concept expands the possibility of constructing nursing interventions aligned with this objective, which is a knowledge gap.
In January 2022, a preliminary search was conducted in the PubMed, CINAHL and JBI databases, which revealed a scarcity of studies on the topic.This motivated a proposal to prepare a scoping review in order to map documents addressing the term "safe mobility" in the literature (8) .Such a study strengthens the movement of scientific production in the highlighted thematic universe, since a scoping review makes it possible to identify gaps in the literature, clarify concepts and summarize findings, in addition to systematizing and disseminating findings that can contribute to practices, policies and research (8) .

OBJECTIVES
To map the constituent elements of safe mobility present in hospital care for older adults.

Study design
This is a scoping review study guided by JBI guidelines, an international research organization that guides systematic reviews (9) .Initially, the review question was established, structured by the acronym PCC -P (population/participant), C (concept) and C (context) (10) : what are the constituent elements of the safe mobility concept in hospitalized older adults at risk of falling present in national and international studies?
The review protocol was registered in the Open Science Framework (OSF), under DOI 10.17605/OSF.IO/EDHF6, and subsequently published in the Online Brazilian Journal of Nursing (OBJN) (11) .
Valuing the writing quality and smoothness of this study, the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) checklist guidelines were followed (12) .

Eligibility criteria
The eligibility criteria are linked to the PCC acronym structure.For population/participant, older adults -individuals aged 60 or older, according to the Older Adult Statute classification (Law 14,423 of 2022) (13) -of both sexes were included.For concept, studies that define, report or provide information on safe mobility -relevant approaches that help or encourage older adults to move safely daily, aiming to preserve functional capacity -and the factors associated with promoting this were included.Studies dealing with urban mobility were excluded.For context, studies that involve the care of hospitalized older adults, in multiple circumstances (clinical, surgical, among others), covering public or private hospitals, small, medium or large, teaching, general, specialized, urban or rural, were included.
The review considered primary research studies, systematic reviews, meta-syntheses and case reports, with a quantitative or qualitative design.Furthermore, reports, institutional texts with relevance in geriatrics/gerontology, books and guidelines published in indexed sources consulted or in gray literature were included.Articles published only as abstracts, letters to of Nursing care for hospitalized older adults -fall accidents versus safe mobility: a scoping review Nicoli EM, Silva FVC, Assad LG, Cardinelli CC, Alves RA, Oliveira SG.
the editor and comments were excluded.No time and language cut-off were established.

Data collect
For data collection, a three-step search strategy was developed.The initial stage, carried out in April 2022, consisted of identifying the search terms, and, to this end, controlled words in health in DeCS (Health Sciences Descriptors), MeSH (Medical Subjective Headings) and Emtree were consulted (Embase Subject Headings).The following terms were included: P (population/participant) -middle aged (pessoa de meia-idade)/ aged (idoso)/old people (pessoa idosa)/old person (pessoa idosa)/ elderly (idoso)/Elder (mais velho)/senior (mais velho)/geriatric (geriátrico)/gerontologic (gerontológico)/older people (pessoa mais velha)/older person (pessoa mais velha)/fall risk (risco de queda)/ fall (queda)/fall reduction (redução de queda)/fall prevention (prevenção de queda).It is important to note that the descriptor "older adult" refers to people aged 65 to 79 years old, therefore, in order not to limit searches to older young adults, indexing terms that covered individuals aged 80 years or older were also included.To list people between 60 and 65 years old, the term "middle-aged person" was included, which refers to individuals aged between 45 and 64 years old; C (concept) -Safe mobility (mobilidade segura); C (context) -Hospital Care (Assistência hospitalar)/Hospitals (hospitais).
Such terms were combined using Boolean operators OR, AND and NOT and used to develop a complete search strategy for CINAHL, which was adapted to the other databases: (MM "Aged") OR (MM "Aged, 80 and Over") OR aged OR "aged patient" OR "aged people" OR "aged person" OR "middle aged" OR elderly OR "elderly patient" OR "elderly people" OR "elderly person" OR "elderly subject" OR "senior citizen" OR senium) AND ("fall risk" OR "Accidental Falls" OR "Accidental Fall" OR "Fall and Slip" OR Falling) AND "safe mobility" OR mobility AND (MM "Hospitalization") OR (Hospitalisation OR Hospitalisations OR Hospitalizations).
The second stage consisted of searching databases, which took place in May 2022.The sources of information were BDENF/VHL, Scopus, CINAHL/EBSCO, Embase, Web of Science Core Collection, PEDro, MEDLINE/PubMed and CAPES Catalog of Theses and Dissertations.
The third stage, carried out in November 2022, referred to examination of a list of references of those articles included to select additional studies.
The study selection and evidence extraction process were carried out in a double-independent manner, with blinding through the use of free and open access Rayyan QCRI.Disagreements were resolved by a third reviewer.The selection was made by reading the titles and abstracts, followed by full reading and checking the references of articles that were the object of study in the research.An attempt was made to contact 16 authors in order to request the full texts to be made available, without success.
For extraction, an electronic form prepared by the authors was used according to previous references, and preliminarily tested, containing the article title, journal in which it was published, authors, language, year of publication, database, country of origin, objectives, study design, population, study location, constituent elements of the safe mobility concept, excerpts with the main results of interest in this review, article reference and other references found.

Data analysis
A qualitative content analysis was carried out with an inductive approach, as recommended by Elo and Kyngas (14)(15) , which enabled the categorization and emergence of topics of interest.Of the 521 articles and one dissertation, 106 were duplicates and were excluded, leaving 416 for reading their respective titles and abstracts.This process led to the exclusion of 355 publications, as they did not meet the inclusion criteria, and the pre-selection of 61 articles for full reading, where six articles were recovered using the snowballing strategy.In the end, 35 works remained that suited the research objectives, as shown in Figure 1.Although the concept is not precise, constitutive elements of the concept were identified, which are related to patients, the institution and the nature of the interventions, as shown in Figure 2.

Contributions to Mobility: Limitations of Seniors Awaiting Discharge from Hospital Care (28) 2012

Canada
Experimental and correlation designs The main objective of this article was to assess the ability of hospitalized older adults to use vestibular information to control balance.The secondary objective was to examine the influence of vestibular function and lower limb muscle strength on mobility.
Seniors awaiting discharge from hospital had impaired vestibular control of balance that was systematically associated with impaired mobility.Assessing vestibular function prior to discharge from hospital could improve discharge planning with respect to management of impairments that threaten balance and safe mobility.
Measure, Promote and Reward Mobility to Prevent Falls in Older Patients (29) 2012 Theoretical-conceptual Not specified A focus on maintaining and improving mobility should been couraged when an older adult becomes acutely ill and particularly vulnerable to permanently losing functional capacity during a hospitalization.More importandy, encouraging routine strength and balance training in community-dwelling older adults should be a priority.
What is the involvement of the nursing team in maintaining and promoting the mobility of the elderly in the hospital?A grounded theory study (30) 2013 England

Semi-structured interviews with 39 rehabilitation professionals and 61 hours of non-participant observation comprised the dataset
To present a grounded theory on the nursing team involvement in the process of maintaining and promoting the mobility of hospitalized older adults.
The nursing team involvement in maintaining and rehabilitating patients' mobility was explained by the central category "care to maintain safety".It identified how the nursing team focused primarily on preventing patient problems rather than focusing on rehabilitation goals.A number of contextual factors in the workplace meant that nursing staff had difficulty engaging in activities to support mobility maintenance and rehabilitation.

Quantitative and qualitative approach combined with medical records extraction. 41 older adults
To describe the fear of falling in hospitalized older adults and its relationship with patients' characteristics and physical function and explore patients' view of associated factors.
Participants described the following factors, organised by social-ecological framework, to be considered when developing alternatives to activity restriction: intrapersonal, interpersonal, environmental and policy.
Implementing a Comprehensive Functional Model of Care in Hospitalized Older Adults (32) 2014 USA

Convenience sample. 866 older adults
To develop a comprehensive model of care to promote physical function in hospitalized older adults.
Implementing a comprehensive functional model of care for hospitalized older adults had a positive impact on length of stay, 30-day readmission rate, and fall rate.The estimated cost savings associated with reducing postintervention length of stay by 3 months was approximately $200.00.

To examine the effect of an in-hospital mobility program (MP) on posthospitalization function and community mobility.
The MP intervention allowed patients to maintain pre-hospitalization community mobility, while those in the usual care group experienced clinically significant declines.Lower living space mobility is associated with increased risk of death, nursing home admission, and functional decline, suggesting that declines such as those observed in the usual care group would be of great clinical importance.

Eat Walk Engage did not reduce the composite primary outcome of any HAC-OP, which affected almost half of older inpatients, although there was a significant reduction in delirium.

DISCUSSION
The extent of available evidence mapped in this scoping review showed that intrinsic factors related to patients are those cited most frequently with regard to promoting mobility.Behavioral factors (2,16,19,21,27,29,31,(33)(34)(35)(36)(39)(40)43,(46)(47) are the most prevalent, being mentioned in around 43% of the texts (n =15). Among them, sedntary behavior (31) and inactivity (46) , social isolation and loneliness (2) , lack of motivation (46) , depressive symptoms (31,39,41) , fear of falling (21,31,37,39,41,44) and concerns about the injuries that falls can cause (44) , in addition to beliefs and perspectives about mobility (37) , such as associating the idea of being hospitalized with staying in bed to recover health or that it is a rule of the institution that patients must remain in their rooms, emerge as factors that limit older adults' confidence, becoming obstacles to mobility promotion.
In this regard, achieving safe mobility presupposes assessing behavioral factors, proposing multifaceted interventions, encouraging social interaction (29,33,47) , such as group meals or activities during the day, together and outside the room, and guidelines verbal and written messages to patients (24,(30)(31)(32)43) tend to motivate them (41,45) and encourage them (30)(31)45) . As  coping strategy, progressive goals can be set (41) , initially encouraging them to perform their basic activities of daily living independently (25) .Furthermore, multidisciplinary involvement is important, since patients who are repeatedly warned about leaving their beds evoke aggressive behavior, in addition to hindering initiatives by older adults (22) .
Another set of factors associated with safe mobility are acute and chronic conditions and illnesses (16,19,22,28,34,36,41,43,(46)(47) .Although one study revealed that there was no influence of comorbidities of Nursing care for hospitalized older adults -fall accidents versus safe mobility: a scoping review Nicoli EM, Silva FVC, Assad LG, Cardinelli CC, Alves RA, Oliveira SG.
Regarding drug therapy (16,34,41) , this must be assessed, paying particular attention to polypharmacy (41) and the prescription of sedatives, psychotropics, diuretics and hypotensives (24) , drugs whose effects make older adults more vulnerable to the fall (2,41) .The greater the number of medications in use, the lower the level of self-efficacy and engagement in preventing falls (47) .Therefore, one must consider the complexity of managing falls prevention and safe mobility of hospitalized older adults, which add to the conditions of senescence and senility, and which, if not proposed appropriately, could worsen patients' condition.
To carry out the exercises, two questions must be considered.The first is nutritional support.While one study revealed that Body Mass Index and nutritional status did not influence the relationship between muscular strength and mobility (39) ; others, on the other hand, revealed that obesity and malnutrition (22,36,(40)(41)(42) are associated with muscle loss, worse physical function and consequent risk of falling, and, therefore, mobilization must be scrupulous (42) .In this regard, particularly in exercises with resistance and strength training, nutritional support is essential so that there is no weight loss (22) .
The second issue is that exercises are planned considering non-maleficence.Promoting physical activity is a simple and non-invasive intervention, with the potential to improve mobility (26) ; however, for it to be safe, it must be dosed so that it does not cause symptoms such as dyspnea, weakness and fatigue (31) .
Safe physical activity prevents the loss of function and physiological reserve due to immobility and accelerates the restoration of functions lost due to acute illnesses (16,46) , even contributing to post-discharge community mobility (18) .It is even recommended that mobilization be started early (21,24,32,45,47) , from the moment of hospitalization, based on an initial risk assessment (30) so that pre-hospitalization is maintained (16) , already intending to plan discharge (28,40) .
However, there are divergences in the literature regarding the designation of the professional in charge of promoting safe mobility, particularly in more dependent patients who require the support of a professional (37) .There is a general consensus that the interprofessional and continuous care approach is beneficial for both the system and the patients (2,16,22,29,42,48) ; however, the texts highlight physiotherapists' and nurses' leading role.
Physiotherapists promote sessions with assessment and treatments that maximize mobility and independence through the prescription and delivery of exercises, contributing to older adults' confidence as they progress and follow-up (21,38,40) .It is understood, however, from the readings, that these are specific interventions.
Nurses greatly close to patients are essential to directly assist and supervise patients in promoting mobility (moving, getting out of bed, walking) (30,33,44) .However, some issues highlighted by nurses need to be highlighted: 1) Lack of staff and overworked nursing (4,42) -there is a need for greater presence of physiotherapy (37) ; 2) Nurses do not feel qualified to provide physical assistance and assess it appropriately (42) (This is one of the reasons why walking is not routinely encouraged, causing, in turn, an excessive dependence on physiotherapy (4) as well as misleading guidance, such as ordered bed rest (44) , even for patients who do not need assistance.Furthermore, many nurses do not understand the validity, reliability and usefulness of mobility assessment measures (4) , just as they do not there are standardized and validated processes to encourage older adults' safe mobility during hospitalization (4) ); 3) Some nurses do not identify mobility promotion as their responsibility, not collaborating with physiotherapists and postponing guidance (4) .
Finally, it is understood that nursing assists in the process of physical and personal care, supporting movement, transfer and basic activities, which require supervision (30) .Nursing assessment is important in the identification of geriatric syndromes (24) as well as in assessment and recognition of fall risk factors, which must be included in a care plan, in addition to risks related to the environment (2) .Physiotherapy, in turn, specializes in movement, handling and rehabilitation, and is responsible for these functions (30) .
Still regarding the challenges to promoting safe mobility, it is important to highlight the lack of financial investments and equipment, such as walking aids (4,31,37,44,46) , which allow greater freedom and safety (36) .Another possibility is gerontechnology resources, such as gait belts (19) , hip protectors (17)(18) , smart walker (17)(18) , fall alarms (17)(18) , anti-slip mat (18) and movement sensors (6) .It is interesting that the nursing team is at the forefront of selecting and testing equipment, integrating new technologies into existing infrastructure so that adverse effects related to mobility are eliminated or mitigated, which favors patient treatment, rehabilitation and safety (17) .
of Nursing care for hospitalized older adults -fall accidents versus safe mobility: a scoping review Nicoli EM, Silva FVC, Assad LG, Cardinelli CC, Alves RA, Oliveira SG.
Furthermore, it is important that the environment is improved (17,34,43) , such as adequate bed and furniture height (24,27,31) ; that the ward structure makes it possible to view several patients at the same time (41) , with open corridors that facilitate walking (41) , high-impact carpets and padded floors that minimize the risk of injury (24,29,41) ; that there is adequate lighting in corridors and rooms (22,32) ; and that the hospital is signposted and maps are made available so that patients can find their way around the institution (36,48) .
Finally, appropriate clothing (19) and footwear (22,32) must be provided, attention should be paid to sleep quality (42,44) , length of stay (20) , age, as advancing age contributes for a greater risk of falling (33) , and integrating the family into the care of older adults, making them facilitators and defenders (31) of safe mobility, supporting and reducing negative feelings (2,22) .
Therefore, mapping the evidence showed that safe mobility is related to the nature of the interventions and non-modifiable and modifiable risk factors related to patients, with modifiable risk factors being subject to intervention.Aspects related to the institution include professional training and qualification, adequate staffing, investment in equipment, technologies and structural reforms, in addition to offering appropriate clothing and footwear that converges with the idea.
During the mapping of studies, it was observed that mobility promotion for older adults was valued as well as early mobilization; however, few studies were concerned with studying how to carry it out safely.In this sense, this gap indicates the need for more studies to be carried out that highlight patient safety.

Study limitations
The limitations of this study involve limiting the approaches of studies on the dimensions of older adults' lives that can influence safe mobility and risks of accidents due to falls, such as cognitive, mental and emotional aspects, in addition to not delving deeper into drug therapy.Furthermore, limitations may be related to the search in a simple number of gray literature sources.

Contributions to health
The review's contribution to health points to changes in the perception of falls prevention in hospitalized older adults over recent years.A study carried out in 2007 argues that, until data on successful strategies were available, minimizing mobility could remain the standard solution for preventing falls (19) , whereas a 2021 study understands that preserving mobility and independence requires some risks of falls (2) .The most successful interventions tested are related to muscle strengthening and balance exercise promotion (27)(28)(29)32,35,(38)(39)41,45) .

FINAL CONSIDERATIONS
Evidence regarding the constituent elements of safe mobility supports that these are related to patients (behavioral factors, conditions, acute and chronic diseases, signs and symptoms, nutritional status, age, balance, muscle strength and quality of gait and sleep pattern), the institution (environmental risks, treatment devices, mistaken guidelines, medications and polypharmacy, resources, clothing and footwear) and the nature of the interventions (related to the family, the patient and the institution), assuming that greater possibilities for intercession are related to the last and involve multiple dimensions.Moreover, safe mobility is an expression of hospital units' ability to guarantee care and protection from fall accidents for older adults.The present review showed, however, that the resources for preparing the environment and health professionals to deal with older adults' specific demands are insufficient.Finally, it is important to suggest carrying out a concept analysis of the term "safe mobility".
